5 Claims. (Cl. 292- 108) This invention relates to hooks of the typeused for locking screen doors and the like, and in particular a hookhaving a shank with a hook formation on one end and an eye on the otherand in which a screw eye is extended through the eye and also a screweye having a latch element thereon which is positioned whereby both thelatch element and screw eye receive the hook formation of the shank.

The purpose of this invention is to provide means for preventingaccidental opening of a hook which also provides locking means toprevent a child opening the hook.

In the conventional type of screen door hook a child often opens thehook and escapes through a screen door or section of a play pen and innumerous instances, where hooks are used to lock doors, particularlywhere it is desired to have the main door open, a blow on the doorlocked by the hook causes the hook to jump out of the eye. With thisthought in mind this invention contemplates a latch provided on the eyeprovided for receiving a hook and having a slot therethrough whereby,with the hook extended through the eye and slot of the latch the latchmay be turned over the hook to positively lock the hook in the eye.

The object of this invention is, therefore, tov

provide latch means on the hook receiving eye of a. screen door hookwhereby the hook is positively locked in the eye until manuallyreleased.

Another object of the invention is to provide latch means for holding ahook in an eye or other holding means that may be applied to hooks andeyes now in use without changing the design or construction of the hookor eye.

A further object of the invention is to provide an improved latch forhooks of the screen door type whereby a hook is positively held in aneye until manually released, which is of a simple and economicalconstruction.

With these and other objects and advantages in view the inventionembodies a plate having an elongated slot therein with a hinged loopprovided at one end and with the loop freely mounted on an eye andpositioned so that a hook entering the eye passes through the slot ofthe plate.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawing wherein:

Figure 1 is a front elevational view illustrating a hook mounted througha screw eye on a door frame and positioned with the hook extendedthrough the latch element and eye with the eye positioned on the surfaceof a door or frame, and

with the latch element illustrated in an upwardly extended position indotted lines.

Figure 2 is a plan view of the hook with the parts in the positionillustrated in Figure 1.

Figure} is a front elevational view similar to that shown in Fig. 1showing the latch in the position of releasing the hook. U

Figure 4 is a plan view showing the elements in the released position.

Figure 5 is a detail illustrating the latch.

Referring now to the drawing wherein like reference characters denotecorresponding parts the hook latch of this invention includes a plateIt] having a roll providing a hub H at one end and an elongated slot I2therein and, as illus-f trated in the drawing the hub is rotatablymounted on a screw eye I 3 and the eye I3 is positioned to receive a hook'll on the end of a shank I5, the opposite end'of which is providedwith an eye It, and a screw eye I! provides mounting means for the hookand extends through the eye [6.

The latch H] is formed as illustrated in Fig. 5 and with the roll or hubll positioned around one side of the eye [3, the rounded outer end l8extends beyond the opposite side of the eye, as shown in Figs. 3 ands.With the latch in this position and with the door closed, the hook I4 isplaced through the slot l2 and eye l3, as illustrated in Figs. 3 and 4whereby the hook holds over the hub H and after the hook is in place inthe eye the latch I0 is flipped over to the position shown in Fig. 1whereby with the hook resting upon the hub II the latch it rests uponthe upper surface of the shank [5.

It will be noted that with the hook partly open as illustrated in Figs.1 and 3 the latch may be raised upwardly to the position indicated bythe dotted lines IS, in Fig. l, but will be prevented from passing overthe upper end of the hook formation, the outer end of the slot l2 comingin contact with the surface of the hook.

By this means the latch element is provided on the screw eye thatnormally receives a hook and in locking the screen door, gate, window orthe like, the hook is placed in the eye in the usual manner and thelatch moves over so that the free end thereof rests upon the uppersurface of the shank of the hook. When it is desired to release the hookthe latch is moved over the upper end of the hook from the positionshown in full lines in Fig. 1 to that shown in Fig. 3, and with thelatch in this position the book may be in-- 3 serted in and removed fromthe eye in the usual manner.

It will be understood that modifications may be made in the design andarrangement of the parts 4 slot in the plate and engage the hook holdingmember, and then pivoted to pass over the hook and engage the shankrearwardly of the hook. 4.
